The composition of the minimal and the full basic data set depends on the variant (WS200 ...
WS600) of the device in question (see below). The same applies to the availability of the
additional measurement commands (aM1!, aC1! Etc.)
Due the applied measurement processes the devices of the WS family will, different from
other sensors described in the SDI-12 document, always measure continuously. This causes
some special properties:
The device does not need a “Wakeup” and does not have a sleep mode. So the
reactions to “Break” signals and any related timings are inapplicable. “Break” will be
ignored by WS devices.
Data requested with M- or C- commands are always available immediately. The
device will always respond with a000n resp. a000nn . This means the device will
not send any service request and will ignore measurement abort signals. The logger
should request the data immediately.
M- and C- command only differ in the number of values made available in the buffers
(in both cases the maximum permitted by the standards of 9 resp. 20).
We recommend to use the commands for continuous measurement (R-commands)
to request the data.
